Plenty of tree nodes.

import { Tree } from 'antd';
import type { DataNode } from 'antd/lib/tree';
import React from 'react';

const treeData: DataNode[] = [];

for (let i = 0; i < 100; i += 1) {
  const children: DataNode[] = [];

  for (let j = 0; j < 100; j += 1) {
    children.push({
      title: `child ${i}-${j}`,
      key: `l-${i}-${j}`,
    });
  }

  treeData.push({
    title: `parent ${i}`,
    key: `l-${i}`,
    children,
  });
}

const App: React.FC = () => <Tree defaultExpandAll height={400} treeData={treeData} />;

export default App;
